A water level control means for a gas cooling or washing chamber 1 comprises a valve closure member 13 connected to the upper end of an elastic or spring-loaded bellows 10 responsive to the head of water in the chamber 1 and arranged to control the pressure in a pipe line 12 connected at one end via a restrictor 14 to the main supply pipe 5 and leading to the interior of a second elastic or spring-loaded bellows 15. The bellows 15 is provided with a closure member 16 controlling a discharge outlet 8 from the chamber 1. When the water level in the chamber 1 rises above a predetermined level the valve member 13 opens under the head of water acting on the bellows 10. The consequent fall in pressure in the line 12 and hence in the interior of the bellows 15 permits the valve member 16 to open under the combined loading of the head of water and the gas pressure in the chamber 1. By this action the level of water in the chamber is reduced to its predetermined value. The bellows may be replaced by spring- loaded pistons.

Abstract: 1,154,736. Control of machine tools. OERLIKON-BUHRLE HOLDING A.G. 31 Aug., 1966 [2 Sept., 1965], No. 38911/66. Heading G4H. In apparatus for detecting the movement of, for example, a machine tool from a fixed datum position, pulses from photo-cells sensing either a scale 17 (Fig. 1) moving with the stand 11 of the machine tool or a rotating slotted disc (75, Figs. 5 and 6, not shown) are not accumulated in a counter until a cam 29 opens a switch 27 by releasing a plunger 28. In the embodiment of Fig. 1 switch 27 is opened just before two photo-cells 24 are symmetrically positioned over the first division line of the scale 17. When the photo-cells 24 are symmetrically positioned over the first division line of the scale a transistor 43 (Fig. 4) in a multivibrator 33 is rendered conducting and transistor 44 is cut off so that the negative voltage on a conductor 54 renders transistor 60 conducting to open gate 34. As the photo-cells move over the divisions 18 (Fig. 1) a transistor 36 (Fig. 4) is rendered successively conducting and non-conducting to apply pulses via conductor 43, transistor 63 and conductor 84 to the counter. In the second embodiment (Figs. 5 and 6, not shown) two photocells (79, 80) sense slots (77, 76 respectively) in the disc (75), the gate (34) being enabled when the first slot (77) is in front of the photo-cell (79).

Abstract: 883,432. Knitting-machines. MACQUEEN CYBERNETICS Ltd., EVERSHED & VIGNOLES Ltd., and BROOKE, E. R. Feb. 27, 1959 [Dec. 16, 1957], No. 39105/57. Class 74 (2). As the cam box 1 traverses the needle bed in the direction of the arrow 2, each jack (or needle) butt 10, of a magnetic material, strikes in turn against the rounded edge 9 of the pole face 8 of an electromagnet moving with the cam box and energized from time to time by electric impulses, according to a predetermined programme, so that any butt which is in contact with the pole face when an impulse is received will be attracted to it, thereby to condition the jack or needle for operation by a cam or cams of the cam box. As the cam box moves along the bed, and because of the inclination of the pole face, any jack so selected will move in the direction of its length into a position 22, whereupon a second magnetic butt 16 on the jack is lifted away from the bed, by one of two permanent magnets 17, into the path of a cam 23 which advances the jack and, through a slider 14 attached to the needle, positions the butt 27 of the needle in the path of a cam 24. The jack is subsequently retracted by the action of a cam 25 on the butt 10, to bring butt 16 into the path of a cam face 26 along which it travels until pushed down into the track by a ramp 19. To assist the action of the magnets 17 in lifting the butts, inclined faces are provided on the abutting ends of jack and slider or needle. The butts 16 of jacks which have not been selected by the electromagnet 4 remain in the path of the downwardly sloping face 18 of a ramp, thereby to prevent the raising of the jack by the magnet 17. The two magnetic butts may be attached to a non-magnetic strip forming the jack body. The butt 27 of any needle associated with a selected jack is positively carried past the point 24a of cam 24, so that no collision between the butt and the point is possible. The impulses may be generated by a reader mechanism co-operating with a punched card or tape, or by a scanning head associated with a magnetic tape or record. The needles may be selected to knit or not, or to tuck or hold. The magnetic part of each butt 10 may be of diamond-shaped crosssection, with alternately sharp and radiused corners; or it may be in the form of a small roller. There may be provided, opposite the pole face 8, a second pole face which is magnetized when the face 8 is not magnetized, to ensure that passing butts shall be held in line with other unseleoted butts. Specification 835,270 is referred to.

Title: Improvements in or relating to rotary relief-type printing presses

Abstract: 891,399. Inking-apparatus. HARRIS-INTERTYPE CORPORATION. Dec. 5, 1958 [Dec. 5, 1957; April 25, 1958], No. 39303/58. Drawings to Specification. Class 100(2) A rotary printing-machine comprises a forme roller for inking a relief printing plate, said roller having a resilient inking member extending over at least a part of its surface, being driven at the same peripheral speed as the plate cylinder, and being dimensionally related to the latter so that the same areas of the inking member always apply ink to the same areas of the plate, and means are provided to maintain the axes of the roller and cylinder in precisely spaced parallel relation to control the pressure at which ink is applied. The forme roller is covered with a multiply make-ready sheet on which an impression is made by the printing plate. Plies proportional to the lightness of tone desired are then stripped away from parts of the sheet. A greater number of plies are stripped away where there is to be no printing as on areas corresponding to the outside areas of the plate. Alternatively the sheet may be one which swells with heat; the impression is made through a carbon sheet, the deposited carbon acting as a heat insulating during subsequent exposure to heat. The sheet is then covered with a resilient blanket. The forme roller is thus of varying effective diameter, and both receives ink from the distributing rollers in varying amounts over various areas, and transfers ink to the plate in varying amounts. Further, the distributing rollers may be at slightly different distances from the forme roller, so that some only of the former contact some parts of the latter. The forme roller and plate cylinder are formed with end bearing members rotating in contact, and are of such diameters that any point on the plate is always inked by the same point on the forme roller. With this arrangement, thin printing plates may be used which are shallow-etched, even the non-printing margins being shallow-etched, without undesirable ink transfer in non-image areas.
